Switching the scope, within a tab, should invoke automatic search
When switching a scope, within a tab, automatic search is not invoked (if the Primo View is configured for automatic search when switching tabs).
This is counter-intuitive because the two dropdowns for tabs and scopes are next to each other but do not behave in the same way. Users are confused when nothing happens after they change the scope.
Here is an example of a Primo View with tabs and scopes. You'll see that changing CSUSM Collection to Media Library does not update the search results automatically. However, changing Books and More to CSU+ invokes the automatic search.

Also true for Primo VE.
At the very least 'Enter' should start the new search.
